input stream operator c++ code example
Example 1: overload input operator c++
#include <iostream>
using namespace std;
class Distance {
private:
int feet;
int inches;
public:
Distance() {
feet = 0;
inches = 0;
}
Distance(int f, int i) {
feet = f;
inches = i;
}
friend ostream &operator<<( ostream &output, const Distance &D ) {
output << "F : " << D.feet << " I : " << D.inches;
return output;
}
friend istream &operator>>( istream &input, Distance &D ) {
input >> D.feet >> D.inches;
return input;
}
};
int main() {
Distance D1(11, 10), D2(5, 11), D3;
cout << "Enter the value of object : " << endl;
cin >> D3;
cout << "First Distance : " << D1 << endl;
cout << "Second Distance :" << D2 << endl;
cout << "Third Distance :" << D3 << endl;
return 0;
}
Example 2: overload the >> operator in c++
istream &operator>>( istream &input, Class_Name &c )
